Characteristics of dust concentration detector alarm:

Intelligent EC sensors adopt intrinsic safety technology and can provide customized products according to user needs. They can achieve sensor interchangeability, offline calibration, and zero point self calibration without the need for tools

Multiple signal outputs, which can be easily connected to industrial control systems such as PLC/DCS, and can also be used as standalone control

■ Large dot matrix LCD display, supporting both Chinese and English interfaces

■ No need to open the cover, operated by an electrochemical remote control, and can be maintained by a single person

Local alarm indication, integrated sound and light alarm (optional)

The instrument has over range and reverse polarity protection, which can avoid the danger caused by improper human operation

■ Rich electrical interfaces for users to choose from
